Sins of a Solar Empire: Rebellion is the stand alone expansion to the real time strategy behemoth that debuted in early 2008. Rebellion brings an immense amount of content to the award winning game and is the perfect starting point for new players in the Sins universe since it contains everything from the Sins universe up until this point. Rebellion comes in at a perfect time to inject some life back into Sins and jettison pilots new and old into one of the best strategy games of its time.

Xbox 360 CoD Elite users will be getting a content drop today for Call of Duty: Modern Warfare 3, with three new faceoff maps (Vortex, U-Turn, and Intersection) becoming available.  But the better news in the content drop is the availability of a new co-op mission called Artic Recon, which is pictured in the above screen.

Inversion may be remembered as a game with one of the most impressive delay histories ever. Despite suffering from at least three delays (four for Europe), it's finally out and the question is were the delays worth it? Find out in our co-op review.

Microsoft's Games on Demand service is infamous for its non-competitive prices. They often cost much more than current retail prices and seldom even go on sale. That makes this week's Games on Demand sale pretty special. Most of the sale games are pretty old, but their prices have been slashed down to just five bucks in most cases. Plus, the sale includes plenty of co-op offerings. I'm talking about Ghost Recon Advanced Warfighter, Perfect Dark Zero, Tornado Outbreak, Cloudy with a Chance of Meatballs, and Kameo, all super cheap this week.

RAGE came out in October of last year and since then, we haven't heard much about the game.  Reviews were across the board, the versus multiplayer was forgetful, and the co-op mode was average at best.  But new rumors suggest the game might be getting a life injection in the form of some new co-op DLC.  Siliconera reports a new ratings submission to PEGI could have revealed some new content...or a new game.

At the start of the year, the A World of Keflings community was given the choice of what DLC they would like to see; swashbuckling pirates, grisly undead, or tooth achingly sweet candy land.  Being the type of manly community that has to shave 4 times a day, they of course picked - Candy.  New images have now been released for this DLC pack in all its pink glory.

Phantom Breaker, the anime-style one-on-one fighting game from 5pb (makers of co-op import Bullet Soul) is due for a western release this fall. It seems 5pb likes all kinds of fighters, as the follow-up game Phantom Breaker: Battle Grounds will be a side-scrolling beat-em-up. Such games usually benefit from 2-player co-op, but Battle Grounds goes above and beyond the call of duty with both online and offline 4-player co-op. A Battle Royale versus mode will round out the multiplayer offerings. Not too shabby!

A new video of Just Dance 4 was released on Youtube not too long ago, sadly disappointing us by its lack of gameplay details with neon-dancer filler.

Recently, Trendy Entertainment has announced its cancellation of Dungeon Defenders for the PlayStation Vita. While we are slightly disappointed by this, Trendy does have other plans already in the works that involve cross-platform gaming.

Terrible news, everyone. Anarchy Reigns, Sega's 16 player brawl-a-rama, has been pushed to 2013. At least two Co-Optimus staff members have gone from "bummed" to "distraught." The worst thing is developer Platinum Games says the game is "finished, localized, and ready to go." Sega has other plans: 

After we ran our Far Cry 3 preview from E3, I noted the Co-Optimus community had some very good questions. Game developers don't hand out business cards at E3 for nothing! I passed along a few questions to Massive's Ditte Deenfeldt, the designer of Far Cry 3's co-op campaign. 

This month's co-op import is not a shmup, nor is it region-locked! Virtual-On Force belongs to SEGA's classic robot battling series. But is Transformers G1-awesome or Michael Bay Transformers-banal? Read on to find out!
